Convert your finance Excel models into a controlled web app

Budgeting, reconciliations, and reporting workbooks — off fragile linked spreadsheets and into a controlled web app with an audit trail.

Finance teams run on Excel — budget models, reconciliations, allocation schedules, board reports. The logic is sophisticated, but when a model grows tabs and external links, it becomes fragile: a broken reference or an overwritten formula can quietly distort the numbers a decision rides on.

We convert those workbooks into a web app that preserves your model's logic and adds the controls finance needs: validated inputs, an audit trail, permissions, and reporting that doesn't depend on one analyst's laptop.

Why it stops scaling

Where finance & accounting teams hit the wall

Fragile, linked models

Workbooks chained by external links break quietly — one moved file and the numbers are wrong with no warning.

Key-person risk

When one analyst is the only person who understands the model, your reporting depends on them never leaving.

No control over inputs

Anyone can type anything into a cell, so bad inputs flow straight into the results.

Slow close and reporting

Assembling the monthly package means wrangling tabs and copies under deadline every period.

What you get

What we build for you

Your model, preserved

The calculation logic you trust, rebuilt in a web app — with validation so inputs can't quietly break it.

Controls & audit trail

Permissions on who can change what, plus a full log of every change, so the numbers are defensible.

Repeatable reporting

Budget, reconciliation, and board reports generated on demand instead of rebuilt each period.

In practice

Example use cases

  • Budgeting and forecasting with controlled, validated inputs.
  • Reconciliations with status and an audit trail.
  • Allocation and accrual schedules in one shared system.
  • Board and management reporting generated on demand.
Questions

Frequently asked

Will my model's logic survive the conversion?

Yes. We start from your workbook, preserve the calculation logic you rely on, and rebuild it in a web app — with input validation so it can't silently break.

Does it reduce key-person risk?

Yes. The logic lives in a documented, multi-user system instead of one analyst's spreadsheet, so the team isn't dependent on a single person.

Is there an audit trail for the numbers?

Yes. Every change is logged with the user and time, which makes your reporting far more defensible than a shared workbook.
